A map can represent the physical structures of which a city is at any one time composed, but the city itself remains uncharted. This is not only because the city will have changed materially by the time the map appears. A map cannot contain the infinite places that the city contains, which come and go along with the people who pass through them. The map is an abstraction, simplifying experiences that are incomparably more variegated.
